Safely Navigate Complex Codebases with DeepSeek-TUI Plan Sessions
Use 'Plan' mode in DeepSeek-TUI to map unfamiliar repositories safely.
Leverage DeepSeek-TUI’s 'Plan' session with DeepSeek-V4 to explore and explain large codebases without the risk of making accidental file changes.
The Scenario
You have just joined a new project or downloaded an open-source repo and need to understand the architecture quickly without accidentally modifying the code.
Before & after
Reading through a new, unfamiliar codebase to understand its structure and dependencies usually requires 1–2 hours of manual exploration and note-taking.
Using the `deepseek-v4-pro` model with DeepSeek-TUI in 'Plan' mode, you can map the repository and identify logic flows in about 5 minutes without changing a single line of code.
The Prompt
[RUN_DEEPSEEK-TUI_IN_PLAN_MODE] "I am new to this repository. Can you explore the current directory, explain the main entry point, and summarize how the [SPECIFIC_MODULE] interacts with the rest of the system?"
DeepSeek-TUI allows users to run V4 models locally or against the API with specific modes like 'Plan' and 'Agent.' 'Plan' mode is specifically designed for repository exploration, allowing the AI to read files and explain architecture before you initiate any changes.
